VISCERA-INSPECTION TABLE.

Specification of Letters Patent.

Application filed July 7, 1919. Serial No. 309,102.

Be it known that I, ELMER KEEBLER, a citizen of the United States, residing at Chicago, in the county of- Cook and State of Illinois, have invented certain new and useful Improvements in viscera-Inspection Tables, of which the following is a specification.

This invention relates to new and useful improvements in viscera inspection tables, and has for its object the provision of such a table the parts of which are readily cleansed.

In the present construction of viscera inspection tables the conveyer of the table is p'assed'through atank for the purpose of cleansing the flights of the conveyer. This is objectionable in that the fluid in the tank soon becomes filled with minute particles of the viscera and as the flights arise from the tank they cling to the surface thereof. In order to prevent this, I subject the flights of the conveyer to the action of jets of water and steam which force the particles from the flights and these particles are removed from the sterilizing chamber in which the cleansing operation takes place so that the flights in passing out of the sterilizing chamber do not come in contact with the particles.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a plan view of my device, a

portion of the flights being broken away to show the arrangement of the sterilizing tank;

Fig. 2 is a section on line 22 of Fig. 1; Fig. 3 is a side elevation of my'device;

Fig. 4: is a. longitudinal section throughv the sterilizing chamber;

Figs. 5 and 6 are perspective sections of the flights; and Fig. 7 is a perspective view of a link. 1

Referring now more particularly to the drawings, the numeral 10 indicates vertical standards connected by transverse supports 11 and an upper trackway support 12.

Secured-to the upper trackway support 12 by means of brackets 13 are angle iron tracks 14 extending longitudinally of the thereon sprocket Wheels 17, the direction of Patented June 7, 19211.,

rotation of the shaft being indicated by the arrow in F ig., 3. At the other end of the device is arranged an idler shaft 18 mounted in a longitudinally adjustable bearing 19 and provided with sprocket wheels 20.

Mounted for travel upon the sprocket wheels 17 and 20 is a conveyer 21 composed of sections 22 having an upstanding flange thereon and sections 24- similar to the sections 22 except that they are not provided with a vertical flange. The edge 25. of these sections or flights are machine finished for a purpose to hereinafter appear. Secured to the bottom of the flights by means of rivets or the like are link connections 26 provided at the connections with the rollers terfering with the operation of the conveyer.

The flights are provided at their ends with supports 28 having mounted thereon rollers 29. It will be seen that the movement of the conveyer is supplied by the engagement of the teeth of the sprockets 17 with the rollers 27. of the sprockets the conveyer is pushed rather than pulled in its operative travel and the machine edges of the flights are forced into engagement affording a very tight joint. The rollers 27 on the upper receiving side of the flight rest upon the trackways 14: and in the return movement of the flights the rollers 29 rest upon the trackways 15. From the foregoing it will be seen that the flights themselves are not brought into contact with any surface which would produce friction. These flights being treated to the action of water are necessaril protected from the action thereof by ga vanizing or the like and any frictional engagement will tend to remove the galvanizing and cause the flights to rust.

Arranged in the path of the returning Due to the direction of rotation flights is a sterilizer casing 31. The flights enter at one endto an opening 32 formed in the casing. This casingis divided into three compartments A, B and C by transverse partitions 33 and 34:. As clearly shown in Fig. 4, these partitions are provided with spring hinged doors 36 and 38. These doors are engaged by the vertical flanges 23 of the flights and open to permit the passage of the same. 1

The operation of mydevice is as follows: As previously stated, the flights in their operative travel are pushed from the loading endof-the table by sprockets 17 afl'ordceiving. and under surfaces from pipes 37,

undue escape of steam from the compartment being prevented by the spring doors 36 and 38. The action of the steam tends to loosen any particle's not removed by the water in compartment A and these particles are removed when in compartment 0 wherethe receiving faces of the flights are again subjected to the action of water supplied from the pipe 39. The flights pass out of the conveyer through the opening 40 in the rear end thereof. As the flights are being pulled during the return 111 vement the joints of the flights are slight y separated and accordingly are easily reached by the steam and water for cleansing. T have shown the bottom of, the sterilizer as being inclined and provided in each of the compartments A, Band C with a drain for the purpose of carrying old the waste material 7 and collected water.

It is to be understood that the form of my invention'herewith shown and described is to be taken as the preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing. from the spirit of the invention or the scope of the subjqined claims. 0
